  • 1. SRI applicationSRI application in Vietnamin Vietnam Farmer group in Thuy Lam Commune, Dong Anh District, Hanoi, applying SRI methods to production of traditional sticky rice Ngo Tien Dung, Deputy Director General – Plant Protection Department (PPD), MARD
  • 2. - Rice cultivation: 7.4 millions ha/year - Rice production: 38.9 mill tons of paddy rice/year - Corn area: 1.14 million ha - Vegetable area: 720,000 ha - Coffee area: 525,100 ha - Sugarcane area: 270,000 ha VIETNAM VIETNAM
  • 3. There are several existing problems in rice cultivation: • Overuse of pesticides • Overuse of chemical fertilizers (especially nitrogen) • High transplanting density BackgroundBackground
  • 4. BackgroundBackground Causing problems: • Rice crop is susceptible to pests, resulting in decreased yield, less economic efficiency, and deteriorating environmental quality. • Pesticides kill natural enemies, causing pest outbreaks • Overuse of chemicals (fertilizer, pesticide, etc.) will pollute the environment, affecting environmental health. Hopper burn
  • 5. • In 2003, National IPM Program Vietnam introduced SRI to the farmers for experimental application. • From 2003 to 2004, farmer groups under IPM/BUCAP auspices applied SRI under various practice conditions • In years 2005 and 2006, SRI was applied in demonstration plots of 2-5 ha that showed SRI having any advantages in comparison with conventional practice (DANIDA support) • In 2007, Vietnam conducted a pilot model of “community- based SRI application” on the large scale of 170 ha in Ha Tay (supported by OXFAM America) • On 15 Oct. 2007, the Ministry of Agriculture and Rural Development (MARD) issued a decision acknowledging SRI as an ‘advanced technology’ BackgroundBackground
  • 6. • From Sept. 2007, OXFAM America launched a 3-year program “Advancing Small Farmers in Mekong Region with SRI” (VIE 034/07) to assist Vietnam for scaling up the SRI utilization • Programme has been conducted in collaboration of the Government and NGOs in Vietnam: the Plant Protection Department under MARD; Oxfam Quebec; and Centre for Sustainable Rural Development (SRD), as well as Oxfam America BackgroundBackground
  • 7. Background: Project since 2003Background: Project since 2003 Implementing agency: Plant Protection Department, MARD Partners: SEARICE, Oxfam America, Oxfam Quebec, Center for Sustainable Rural (SRD), Oxfam Belgium, Hanoi Agriculture University, Thai Nguyen University, Women’s Unions, Farmers’ Union, Japan International Volunteer Center (JVC), World Vision, FAO regional Vegetable IPM Programme Donors: Oxfam America, Denmark (DANIDA) Trainers active: 294 government; 43 farmers 2010 SRI area 286,053 Farmers applyFarmers applyinging SRISRI in 2010:in 2010: 781,282781,282 (( 7171 % female)% female) Main crops: Rice, potato, soybean

  • 9. • Community-based Farmer Field SchoolCommunity-based Farmer Field School (FFS)(FFS) Approach:Approach: Purposes: • Strengthen farmers’ capability with self-developing mechanisms to manage their resources. • Institutionalize SRI applications in the commune level
  • 10. Develop- ment of SRI should go through a series of stages Steps to utilize SRI: Farmer group in Hoa Binh Province doing observations in their study field
  • 11. Steps to utilize SRI: Full draining of the field 1st stage (first season activities): study the principles of SRI through the Farmer Field School (FFS) process with farmers managing together a trial/demonstration field Young seedlings
  • 12. 2nd stage (2nd and 3rd season activities): practicing the utilization on SRI in a larger scale (within 5 ha) Steps to utilize SRI: Making the beds 2 meters wide Canal made between two beds
  • 13. 3rd stage (after two or three seasons): extension of SRI in the whole community Steps to utilize SRI: SRI applied in 50 ha of traditional sticky rice in Thuy Lam Commune, Dong Anh District, Hanoi, in summer crop season, 2010
  • 14. • 4th stage: farmer groups will continue to improve SRI techniques and improve cultivation practice in order to have better production and better market access. (Stage 4 can be incorporated in stage 3) Steps to utilize SRI:
  • 15. Burning straw and stubble might kill natural enemies and harm the soil ecology; also health hazard
  • 16. Farmers develop minimum tillageFarmers develop minimum tillage with potato productionwith potato production Basal fertilizer application Mulching Farmers observe agro-ecosystem
  • 17. Farmers develop minimum tillageFarmers develop minimum tillage with potato productionwith potato production In comparison with conventional practice, these new practices: - Reduce soil preparation labor by 40% - Reduce harvest labor by 70% - Increase yield by 8.3-20% - Increase profits by 31%
  • 18. Develop rice production in compliance with VietGAP standard SRI FFS Alumni in Dong Phu Commune, Chuong My District, Hanoi, cooperate with a private company to develop rice production in compliance with VietGAP (Good Agricultural Practice) standard

  • 30. LimitationsLimitations • SRI irrigation management needs a strong collaboration among the community • Financial support for expansion is still limited • Organic manure resources are limited; need to make better use of straw and other biomass to reduce fertilizer need
  • 31. Strategy:Strategy: • Strengthen collaboration with Cooperatives, Mass Organizations (Farmers’ Unions, Women’s Unions, Youth Unions…) for better support of farmer groups to develop SRI in their localities • Priority is given to women’s participation in the learning process to improve their knowledge and skills needed to identify problems and find solutions to solve problems.
  • 32. Strategy:Strategy: • Diversify the communication work in order to disseminate and share better the experiences and achievements of SRI among communities and to advocate the policy support for SRI expansion • Build up the core farmers as resource persons in each commune • Study the potential and conditions for market access of SRI produce (higher quality)
  • 33. • Develop weeding and aeration tools for local conditions, and improve their supply • Improve soil ecology: minimum tillage, inter-cropping with beans, adding green manure crop Strategy:Strategy:
